Be it known that I, DAVID GnssNnR, a citia of the United States, and a resident of orcester, in the county of Worcester and rate of Massachusetts, have invented cerin new and useful Improvements in Means S sling the Ends of Rolls of Cloth, of hich the following is a specification.

Sl/Iy invention relates to new and useful W improvements in means for sealing the ends of rolls of cloth in preparing them for wet treatment, such as given by the apparatus of my Patent No. 988,703, April 4:, 1911.

In my said patent I have shown and described a new and improved apparatus for wet-treating cloth in roll form, it being understood that the cloth must first be wound upon a perforated receiving cylinder before being placed into the said apparatus.

The perforated receiving cylinder 30 is shown in the drawings of said patent without any cloth wound upon it, because the winding on of the cloth upon this cylinder before wet-treating, and sometimes also the unwinding of the cloth therefrom after wettreating, is done in a separate and different machine, such for instance, as illustrated in my Patent #994,07 5, May 30, 1911.

After winding the cloth upon a perforated receiving cylinder, for wet treatment, a few yards of cotton cloth are wrapped on the outside of it as a means for protection. The cotton wrapper used for this purpose is usually considerably wider than the cloth, and the protruding ends of the wrapper are well drawn down over the ends of the cloth roll, so as to protect them as thoroughly as possible, a rope being used generally for tying down the wrapper outside the cloth 40 roll and the ends thereof. This tying down of the wrapper has to be done by an experienced and clever hand, if the wet treat ment following it is to result satisfactorily. When the tying is done slovenly, or imperfectly, unevenness of work is sure to follow, such goods showing uneven shading when subsequently dyed any other color than black. The thing for the operator to observe then at all times, according to the old practice, is to tie the rope at the ends of the roll in such a manner as to make it impossible for the water, when pumped through the perforated receiving cylinder, to issue with greater force or freedom from or through the ends of the roll of cloth, than through, or from the rest of the body of the cloth roll. It is very difficult to obtain operators who can do this work satisfactorily, and when done properly much time has to be spent over the job, and that meansavery small production. Hence, most mills keep on dyeing the bulk of their goods black, whereas they would put out many more light colors, if only they could get uniform results in dye ing. To escape this continuous trouble of uneven shading of colors certain mills resort to dyeing their goods before wet-treating them. In that case, however, the goods shrink too much in dyeing, for the main object of wet-treating is to set them so they shall not shrink too much in the subequent process of dyeing.

N ow, the object of my present invention is to enable the mill man to properly wettreat the goods without fear of uneven shading of colors later on, and which will not require the labor of skilled operators, but which will make it possible for an inexperienced man to give even superior results, and furnish a decidedly greater amount of work, than can be accomplished by the most expert mill hand who has to resort to the methods heretofore known, and heretofore 1n vogue, for tying down the wrappers of cloth rolls for wet-treatment.

To carry out my invention I employ, near the ends of the cloth-receiving roll, a pair of detachable circular heads, preferably made in sections, that can be bolted together along their division lines and thus be made to grip tightly around the cloth-receiving rollbody, just beyond, and in close proximity to the selvages of the cloth and the overlapping wrapper, the

union between these heads and the roll body being preferably rendered absolutely air and water tight, when the sections are assembled in place. These heads have circular faces for receiving a layer of flexible band or tape, shown as being preferably of equal width with the width of these faces, and

carry flanges preferably extending radiallyof the heads outward from these faces for guidance, so as to insure the various lengths of tape to lie in a straight circular line, during winding, and thereafter. Different sizes of heads, and different lengths of tape are employed to accommodate varying diameters of cloth rolls, formed either larger or smaller, by the ever changing weights, thicknesses, or lengths of material presented for treatment. My object for winding variable preferablylayers of a flexible band or tape around the V vening gap between the ends of-the cloth] roll and the adjoining heads by connecting to the tape covering the faces of the heads,

a bridge-band sufiiciently wide to cover "not only the tape-covered faces of the heads themselves, but covering also, and binding down, the margins of the enwrapped clothroll, for a distance reaching slightly beyond its selvages in order 'to thus securely seat up its ends and to make certain, when the water is pumped through the cloth-roll, that it must issue directly through it radially, without escaping at the sides, or ends thereof.

I have fully and clearly illustratedimy invention in the accompanying drawings, to be taken as a part of this specificatiom'and wherein; I

Figure 1, shows in cross-section one of the perforated cloth-receiving cylinders 30,- used in a wet-treating apparatus such as ,described in my Patent No. 988,703, with a number of pieces of cloth wound upon it and encircled byva cotton wrapper turned 7 down at the sides, and placed against the ends of the cloth-roll may be seen the sections oftwo circular sealing-heads with a layer of tape" wound upon their faces and a bridge-band drawn over thetape and the edges of the enwrapped cloth-roll, shown in 1 cross-se ction; Fig. 2, represents two sections of the circular sealing-head bolted together with a portion of the web and flange'of one section removed, thus exposing to view part of its face shown in cross-section; Fig. 3, is a front view of one section of a sealinghead, with the tie-bolts thrown back; Fig. 4:, simply shows an enlarged cross-sectional view of the-corner of a cloth-roll and its adjacent sealing-head with tape and bridgeband in place Fig: 5, shows a detail.

Referring to the figures of the drawings just mentioned, 30 is the perforated clothreceiving cylinder, upon which are wound in roll-form one or more pieces of cloth a,

I around which cloth-roll are lapped several layers of acotton-wrapper Z), with its overhanging ends 0 turned" down over the edges of the cloth; The circular sealing heads d' are sopl'acedupon the perforated cylinder-v 30- as to bring thefin-n'er edge e" of the annular f'acef of the' heads close up. to and in engagement with the turned down ends 0' of the wrapper, leaving an open space g I between the'web hof'the heads and the ends ofthecloth-roll.-, The face if on each head is preferably provided by forming the inner faceoftire -head with an inwardly-projectface of which constitutes said face f". The

heads, and filling the space between the I one of the pockets Z in the face of the seal gage with the hooks gfastened upon the in mg annular flange the outercylindrical surheads'are preferably made in'separablesections, ;formedwith radial abutting flanges d adapted to be clamped g her by any suitablemeans, as for instance,;the swingrbolts;

d pivoted to one of said sections and adapt-f i ed to engage the other section and-"be whereby said sections are clamped around" the cloth-roll. Thesections cl Iareforme'd with'curved recesses (l -at their central 'por-Y tion, which, when the sections are assembled 7 combine to form a circular opening within which the cloth-roll 30 is received; 'Bythe arrangement described of securing theheads 'on the roll they are readily adjustable lengthwise of the roll to'cloth of" different widths. Each of the heads dis extended be-f f1; I yond the face f to provide a circumferenefSS l, tial radial flange (Z which isspaced from i the end of the cloth when the edge *e is engaged with the cloth. 7 1 'The annular face f'has a shallow pe-i ripheral groove '1; cut around its middlepor-f tion, and contains a number of undercut V i shaped pockets Z spaced around its periphery and extending transversely of said face, into any ofwhich'pockets may be en:

fastened at-the extreme end of the band or tape n for covering the faoef of the sealing-g1 outer, edge portion of the heads, that is the.- flanges cl and the ends of the cloth' 'rolll Fastened to the under side of the band or tape a, and extending-for a lengthequal to a the circumference of the face of the sealing-head, is a narrower piece of tape,-or-' tongue 0, which practically fills the shallow" groove 2' when the hook m is inserted into ing-head whenever the tape is Wound around i it. By this arrangement the pressure of the tape against the edges ofthe groove as sists' in making an efficient seal between thei said face andthe tape, and the operator is' able to start the tape straight when winfd ing it in'placen At the othenextremity of the tapen'are secured the eyes'p, which en ner or the starting-end of the bridge-band which is' drawn down tightly around -thej tape at, and the corners of the enwrappe cloth-roll, thus bridging-over and' com pletely sealing the jointvor crack *betwee the ends of the cloth roll and" they heads Although not shown in the drawings, a can vas beltwitha buckle orv any other" fasten ing means may be employed outsideof: th bridge-band to keep its end from slipping and the band from losing its grip'aroundf the face-tape n of the'sealing he'ads d. and

the end of the enwrapped'cloth rolll V For conveniently lifting a cloth-loade cylinder 30, I place around the flanges d of the heads a steel rim or ring .9 secured by screws u, and form openings 2? in the flanges (5, so that a hook from the lifting-chain of a crane may be inserted under the steel rim 8, which is made amply strong to sustain any weight ever likely to be put upon it.

In the operation of apparatus such as shown and described in my Patent No. 988,703, after a cloth-loaded perforated cylinder 30 has been put into place, water is turned on until the cloth roll is completely submerged in it, whereupon a pump is operated for drawing the water surrounding the cloth-roll through the layers of cloth surrounding the perforations of the cylinder until exhausted. When the ends of such a cloth-roll are effectively sealed, as just described, the water surrounding it will work inward and fill the spaces 9, but as soon as these are filled, the water will be drawn steadily and straight toward and through the perforations in the cylinder 30. Reversely, when water is pumped into the interior of cylinder 30 it will quickly fill the spaces 9, but once filled, the water in these spaces will form as solid a resistance to any further onrush of water issuing from the perforations underneath the cloth, as the walls of the sealing-heads themselves offer, and once the spaces 0 are filled, all following water. will be forced straight toward the outside of the enwrapped cloth-roll wherever it is not sealed by the bridge-bands r. Thus I get a uniform treatment of the fabric, no matter in what direction the pumps may be working, and when a fabric so treated is dyed afterward, no uneven shading of colors will result, as is the case where the tying of the end of a cloth roll with its wrapper is left to the ingenuity of a skilled workman, who depends upon the winding of a mere rope for sealing the ends, with disastrous results, except where black colors only are concerned.
